Pile of kids walking by?

I was sitting here watching TV online thinking of ideas of snacks to bring with us. I heard all these kids yelling and laughing. Now I am staying in town, but it has neverbeen this noticeable, or loud at least.
The one dog is standing at the front door staring out whining. I thought what is he doing, and I look out and see about 60 kids walking down the sidewalk.
